Let's divide 30335013 by 807
The aim is to understand the frequency of 807 in 30335013.

On to step 1:
If we divide 3 by 807, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 807

Moving on to step 2:
When dividing 30 by 807, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 807

On to step 3:
When dividing 303 by 807, we get 0 with a remainder of 303.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 303, we get 303.
Take the next digit (3) from the dividend and append it to 303, then repeat: 3033 / 807

On to step 4:
When dividing 3033 by 807, we get 3 with a remainder of 612.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 2421 from 3033 to get 612.
Append the next digit (5) from the dividend to 612 and continue with: 6125 / 807

On to step 5:
The number 807 fits into 6125 7 times, leaving a remainder of 476.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 5649 from 6125 to get 476.
Take the next digit (0) from the dividend and append it to 476, then repeat: 4760 / 807

Moving on to step 6:
807 can be fit into 4760 5 times, resulting in a remainder of 725.
Write down 5 as next digit of the result. 
Result so far: 375.0
Subtract 4035 from 4760 to get 725.
Fetch the next digit (1) from the dividend, attach it to 725 and continue: 7251 / 807

Going ahead to step 7:
7251 divided by 807 is 8 with a remainder of 795.
Use 8 as the next digit of our solution. 
Result so far: 3758.0
Deduct 6456 from 7251 and we're left with 795.
Fetch the next digit (3) from the dividend, attach it to 795 and continue: 7953 / 807

Moving on to step 8:
If we divide 7953 by 807, we get 9 and a remainder of 690.
Use 9 as the next digit of our solution. 
Result so far: 37589.0
Subtracting 7263 from 7953 leaves us with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 9:
807 goes into 6900 8 times with a remainder of 444.
The next digit of our result is 8. 
Result so far: 37589.8
Deduct 6456 from 6900 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 10:
4440 divided by 807 is 5 with a remainder of 405.
Write down 5 as next digit of the result. 
Result so far: 37589.85
Deduct 4035 from 4440 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Moving on to step 11:
The number 807 fits into 4050 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 37589.855
The remainder is 15 after subtracting 4035 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 37589.855 with a balance of 0.0015.
